Severe sepsis and septic shock despite recent advances in surviving sepsis campaign remain encumbered by a high mortality rate close to 30%. One cornerstone of the management of these patients remains the early and appropriate antibiotic administration, , which must be also active at the site of infection. Aminoglycosides are often administered in combination with beta lactams in this context . According to the progress in pharmacokinetic management achieved over the past decade, their safety and efficiency tended to increase but many uncertainties remain. The purpose of the present study is to determine whether administration of aminoglycosides in septic critically ill patient is a risk factor for acute kidney injury.
